FEED CONTROL FOR OIL-BURNERS.

Application filed February 10, 1915.

To all whom it may concern:

Be it known that I, JULIUS \V. Knorr, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Feed Control for Oil-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the acconipanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to burners of the type particularly adapted for the burning of crude oil. It is found in the use of burners of this type that more or less of the sediment contained in crude oil will find its way through the filtering means commonly employed and will clog the control valve in the passageway leading to the burner or burners due to the necessarily restricted nature of the valve passage. It is also found that while burners of this class, having a single burner, work more or less satisfactorily, those having two or more burners are not satisfactory in their operation, for if one burner becomes more highly heated than the others, or if it is desired to light one burner while another burner is in operation, the oil will be drawn to the more highly heated burner, or the one in operation, thereby llooding it and depriving the other burner or burners of the necessary oil for burning.

The object of my invention is the provision in connection with an apparatus of this character, of improved means for controlling the flow of oil to the burner or burners thereof, whereby to prevent a clogging of the feed passage by oil sediment therein, and also to effect a proper feeding of oil to one or more burners, as desired, whereby to render burners of this type particularly ellicient and economical in their operation.

The invention is fully described in the fol.- lowing specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment Specification of Letters Patent.

thereof is illustrated in the accompanying drawings, in which,-

Figure 1 is a front elevation of a stove embodying my invention with a part broken away. Fig. 2 is an enlarged detail of the portion of the device embodying my invention. Fig. 3 a central sectional view thereof. Fig. l is an enlarged detail of a portion thereof with a control valve in section, and Fig. 5 is an enlarged sectional view of the burner portion proper of the apparatus.

lieferrii'ig to the drawings, 1., designates a supply tank or storage chamber for crude oil or other fuel being used, and 2 the outlet pipe from such. tank, which pipe leads into a liltering member 3. This filtering member has an outlet pipe or passageway 4- near its bottom, and, in the present instance, is provided intcriorly thereof with a filtering screen 5 through which the oil is required to pass in its passage from one to the other of the pipes 2, :l. i. considerable portion of the sedii'nent in the oil is filtered therefrom within the member 3, but it is found in practice that some of the sediment works through the screen or filtering medium and into the outlet passage 4.

The control valve for the burner or burncrs, as the case may be, in the present instance, comprises a tapered lug-form of valve (3, which is mounted in a receiving opening in the pipe 4 transversely of its passagcway and is provided transversely therethrough with a passageway 7, which, upon a turning of the valve, may be placed into or out of register with the feed passage l. The lower end of the valve passage 7 preferably of a size substantially equal to the feed passage l while the opposite end of the valve passage is restricted as at 8, to a size suitable to permit a sullicient passage of oil therethrough to supply the number of burners used. If it is only desired to use a portion of the burners, the valve may be turned to cut off a portion of the restricted passage 8, as is well understood in the art, and as indicated in Fig. 4. The restricted portion of the valve passage will not readily clog up with oil sediment, as a large portion of such sediment will pass theretlniough. Should the passageway s, however, become closed at the restricted side of the valve, by the accumulation of sediment therein, the valve may be given a half turn to place the large end of the valve passage in position to receive the accumulated sediment, after which the valve is again returned to its normal posi tion, thus permitting the sediment to flow downward from the large end of the passage 7 through the feed passage, thereby preventing the permanent clogging of the passageway, which is so objectionable in burners of this type.

The valve 6 is preferably provided at one end thereof with a control arm 9, which is preferably of spring form and has a lip 9 projecting from its upper end in position to receive the thrust of an adjusting screw 10, that is threaded through a lug 11 on the feed pipe 4. By turning of the screw 10 a very fine adjustment of the valve 6 may be obtained. IVhen such adjustment has been obtained the valve can be closed without disturbing the same by moving the arm 9 in one direction or the other relative to the screw 10. If it is desired to move the arm 9 to the right, the yielding nature of the same enables it to be sprung outward to move the lip 9 out of register with the screw 10 and boss 11.

The pipe or passage 4. is provided below the valve 6 with a restricted passage 12, which permits a dropping or slow flowing of oil therethrough. In case the feed passage 4: is connected with two burners such passage is provided below the drip passage 12 with two branches 13 and 14 leading to the respective burners 15 and 16. A fork or crotch portion 17 connects the lower end of the pipe i to the pipes 13 and 1%, and rising from the lower central or crotch. portion of the member 17 within the same is a spring deflector tongue 18. T his tongue extends up within the feed passage adjacent to the lower end of the drip passage 12. An adjusting screw 19 is threaded through a side of the member 17 in contact at its inner end with a side of the tongue 18 and is adapted to effect an adjustment of such tongue relative to the drip passage 12 as the feeding of oil to one or both of the burners 15, 16 may require. If it is desired to feed oil to both burners the tongue is adjusted so that its upper end stands centrally under the drip passage 12, thus causing the drops of oil as they fall onto the tongue to be divided and to pass equally to opposite sides of the tongue and into the pipes 13 and 14, thus giving the burners an equal supply of oil. If only one burner is to be used, the spring tongue is adjusted so as to stand at one side or the other of the drip passage 12 thereby causing all of the oil passing therethrough to enter the desired one of the pipes 13, 14.

It is found that the tongue 18 provides a positive dividing means for the oil so that if both burners are being used and one is more highly heated than the other, the oil will not be drawn to the more highly heated burner so as to effect a flooding of it and a starving of the other. In order that the dropping action of the oil on the upper end of the deflector tongue 18. may be observed, the pipe 14 is provided below the drip passage 12 with a sight-glass 20, which closes windows or openings formed in opposite sides of the pipe.

21 designates a torch which may be hung on the upper end portion of the pipe 4 and used for heating such pipe when it is cold and the oil does not flow freely thereto.

I wish it understood that my invention is not limited to any specific construction or arrangement of the parts except in so far as such limitations are specified in the claims.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is,

1. In an oil feed passage, a rotary valve having a passage therethrough adapted to be placed in register with the feed passage, said valve passage having one end restricted and its other end enlarged, whereby when the restricted end becomes clogged with sediment the enlarged end can be turned to receive such sediment and then turned to normal position to permit an outward passage of the sediment through the feed passage.

2. In an oil feed passage, a valve having a passageway for registering with the feed passage, said valve passage being restricted at one end for the purpose described, a spring arm projecting transversely from the outer end of said valve, andan adjusting screw for coacting with a part of said arm to adjust it and the valve.

3. The combination with means forming a fluid feed passage having branching parts,
